AlphaSight Service
Proactively navigate complex reservoirs across all resistivity environments
AlphaSight Service provides superior measurement sensitivity and certainty for confident reservoir mapping.
The TruSight? intelligent slimhole MWD service enhances drilling performance by combining definitive dynamic surveys, high?resolution azimuthal GR imaging, integrated APWD downhole measurements, and AI?driven high?speed telemetry into a single, high?efficiency system engineered for deeper, more complex reservoirs. Designed for demanding drilling environments, the TruSight service delivers reliable, high?speed data that supports confident operational decision making while reducing NPT and overall operational risk.
By delivering definitive dynamic surveys, the TruSight tool eliminates survey?related idle time during connections, reducing flat time and accelerating overall well construction.
The TruSight service acquires wellbore surveys, azimuthal GR, annular pressure and temperature, and shock and vibration data while drilling. The service also enables pumps-off pressure and equivalent static density acquisition, reducing uncertainty in leakoff and formation integrity test interpretation.
Continuous identification of drilling dysfunctions—including shock and vibration and HFTO—helps prevent BHA damage, extend tool life, and reduce unplanned NPT, directly supporting improved well productivity and return on investment.
These capabilities are particularly critical in high?risk extended?reach, deepwater, and HT and HP applications, where managing NPT exposure and maintaining well construction efficiency are essential to asset performance.
The TruSight service combines advanced surveying, high-speed telemetry, and geosteering with drilling dynamics into a single, comprehensive solution for today’s drilling challenges. Definitive dynamic surveys provide uninterrupted trajectory updates in real time, eliminating static survey stops and enabling smooth progress through long laterals, deeper targets, and complex 3D paths. This advanced tool uses 16-sector azimuthal GR imaging to detect formation changes and structural features for precise geosteering and well placement. The integrated APWD module delivers real-time annular pressure data to spot early stability risks and adjust drilling parameters securely. To maintain awareness, high-speed intelligent telemetry reliably transmits trajectory, formation, and pressure data in challenging conditions. Built-in diagnostics monitor shock, vibration, and HFTO, providing early warnings of dysfunctions that could affect performance or tool integrity. A high-power BHA support system ensures stable operation of all LWD tools, enabling longer runs and consistent performance in high-temperature environments.
